Mr. Pham Hong Vinh considers as Vietnam master of glass painting which is began with the simple sketches. The sketching is scanned into the computer design system where Mr. Vinh was outlined his drawing to cater for carving on the glass then. With 24 years in the trade now, Mr. Vinh is the first person making glass painting in Vietnam. He said that technologies have made his job much easier. A specialized laser print will draw the outlines onto a sheet of sticky back plastic and this in turn will be pasted onto the glass to create the base for carving to begin.
Before, he used to be in the ceramic trade, where he would mold embossed paintings on the surface of the ceramic. He later found that he could apply the same techniques but in engraving upon glass and the later, on adding color, before also putting it in a kiln.
After that, this is often the dustiest part. The artisans use sand in the sand blast on to carve on glass flashy. Then Vinh will polish the carving to ensure a smooth surface. An essential step among the eight-part routine is painting to ensure not only vibrant but also sustainable coloring for the glass. According to Hai Ha who has been working as the workshop of Mr. Vinh for 10 years, this job requires the aesthetic eye. When we paint onto the glass, we do it from the back surface. Thus we are actually carrying out the whole process in the opposite direction of the original paintings. It is the most difficult part and we have to employ our imagination. In other trades, the process of drawing is rightwards, whereas in glass everything is backwards.
When we paint, we paint on the backside, but what we will see in the end is on this side. After the painting process, we will put the glass sheet into the kiln at a degree of 700 degree Celsius. The colors will melt and cling onto the glass surface. The glass can then withstand all weather conditions, whether it is wind or rain, any types of chemicals or any kind of collision. This glass has attained what people call “eternal sustainability”.
